Description
本創作係一種列車噪音隔離裝置及列車噪音隔離方法,尤指應用於列車行徑路段並提供降低噪音之效果的列車噪音隔離裝置及列車噪音隔離方法。This creation is a train noise isolation device and a train noise isolation method, especially a train noise isolation device and a train noise isolation method that are applied to a section of a train and provide a noise reduction effect.
列車為日常生活中,提供人們長距離移動之主要的大眾運輸工具之一,然而當列車行進於軌道上時,列車行經軌道之間的接縫處以及在過彎的過程中,車輪與軌道之間的碰撞與摩擦會產生出高分貝的噪音,進而導致居住於附近的居民深受其擾。The train is one of the main public transportation means for people to move long distances in daily life. However, when the train travels on the track, the train passes through the seam between the tracks and during the process of turning, the wheel and the track The collision and friction between them will produce high decibel noise, which in turn causes residents living nearby to be deeply disturbed by it.
而為了減少列車行經軌道之間的接縫處以及在過彎時產生之噪音對周遭居民之影響,現今的作法係透過在容易發出噪音之彎道或有軌道接縫之的路段二側分別設置一道隔音牆,當列車行經設有隔音牆的路段時,列車行經所發出的噪音能被隔音牆所組隔,使噪音的聲波部分反射,並僅使部分的噪音聲波透射過隔音牆,藉此達到減少列車行經時產生之噪音對周遭居民之影響,然而隔音牆所能提供減少噪音之效果有限,當列車行經時所產生的噪音仍會對周遭居民造成影響。In order to reduce the impact of the joints between the trains passing through the track and the noise generated during the cornering on the surrounding residents, the current practice is to install them on the sides of the roads that are prone to noise or on the sections with track joints. A soundproof wall. When a train passes through a section with a soundproof wall, the noise emitted by the train can be separated by the soundproof wall, partially reflecting the sound waves of the noise, and only allowing part of the noise sound waves to pass through the soundproof wall, thereby To reduce the impact of the noise generated by the train on the surrounding residents, however, the noise reduction wall can provide a limited noise reduction effect, and the noise generated when the train passes will still affect the surrounding residents.
